Should I file a separate return for my son due to him receiving 1099-Bs?

Greetings! My son has net capital losses of - $14 for year 2022 and no other income. I am claiming his as a dependent.

He received three official forms 1099-B from the three brokerage firms he traded stocks with. 

Question: Should I file a separate return for him due to the fact that the three 1099-B's are sent to the IRS?

Age: 22 in 2022
Occupation: full time student

Thanks much!
